rMPRovnMnn-Tm HORSE HAY-Forms.

The Schedule referred to in these Letters Patent and making part f the same.

Beit known `that I,JOHN S. YINGER, of Manchester, ,in the county of York and State of Pennsyluseful Improvement in Horse Hay-Forks, the same being more especially designed as an improvementv on the horse hay-fork for which Letters Patent of the United States were granted to me December 29, 1868; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had tothe accompanying drawing forming part of this specification.

Figure lis a side view of my improved fork in position for raising hay. Y

Figure 2 is a side view of' fthe samel in position for being thrust into the hay.

Similar letters of reference indicate corresponding parts. I

'My invention has for its -object to furnish animproved horse-hay-'ork, whichshall be simple inconstruction, strong, durable, not liable to get out of order, and conveniently operated; and

It consists iu the construction and combination of the various parts of the fork, as hereinafter more fully described.

A and B are the tines of the fork, which are made in about the shape shown in figs. 1 and 2, that 4is to say, their lower parts are curved, as shown, and their inneror` concave sides, toward their points, are corrugated or notched. The middle parts of the tines AI l 'B are straight, and incline slightly upward from the 'lower or curved parts of the tines to their upper parts or shanks.

The shanks of the tines A B extend upward, nearly ,parallel with each other', when the fork is closed, and their upper ends are pivoted to and between the lower ends of the plates C, between the upper ends of which ing-rope E passes.l

The hoisting-rope E is kept in contact with the is pivoted a concave roller, D, around Which the hoist- 'roller D, and is kept from coming in Contact with' the pivoted upper ends of. the4 tines A B, by a rivet, c', vwhich also serves 4to connect and strengthen the plates'.

The edges of the plates G are notched upon `one side to receive the ring 'F, attached to the lower end To the lower ends ofthe lever G are pivoted theE bars or rods I, which pass across to the opposite sides o'f the shanks ofthe tines A B, and are pivoted to the eye of the eye-plate J, which passes along the outer edge of 'the shank ofthe tine A, and is secured in place by bands passing around it, and around the said shank of' the tine A.

'lo the upper part of the side of the lever G, just at the base of the hook g', is pivoted a small triplever, K, to theouter end of which is attached the -end of Jthe trip-rope L.

Ihe trip-rope L passes around a pulley, M, pivoted to the middle part of the tine B, near 'the curved lower part of the tine B.

The trip-rope L passes over a pulley, N, swiveled to the plate C, and it is extended into such a position that it may be conveniently reached and operated by Vthe operator. A

It should be -observed that the upper ends of the plates G are curved a little toward the lock-lever. G, to bring the hoisting-rope E, when supporting the fork, directly above the center of said fork.

In using the fork, the tines A B are spread apart into the position shown in iig. 2, and are thrust to the desired depth into the hay. The ring F is then hooked upon the hookg of the lever G, and the horse is started up. As the hoisting-rope E is drawn, the first ei'ect is 'to draw the lever G into the position shown in fig. 1, closing the tines until thel sides of the ring F rest against the edges of the plates C. As the hoisting-rope continues to be drawn upon, the loaded fork will be raised andtransported to the place where the hay is to be deposited. The trip-rope L is then drawn upon, which operates the trip-lever K, and raises the ring F out of 'the hook g of the lever,` G, allowing the weight ofthc hay to spread the tines A B, and drop to its place. The fork is then drawn back by the trip-rope'L, to be again loaded.

Havingthus described my invention, l

I claim asA new and desire to' secure `,byf'Letters Patentl. The-arrangement, with the plates C and the upper ends of the shanks of the tines A and B, of the hooked lever G, tri p-lever K, connecting-rod I, bracket H, and eyefplate J, as shown and described.

2. An'improved horse, hay-fork, formed by the combinationrof the tines A B, plates O, concave roller D, ring F, hooked lever G g', bracket H, connecting-rods or bars I, eye-plate J, trip-lever K, and pulleys M N with each other, said parts being constructedand operating substantially as herein shown and described., and for the purpose set forth. i v JOHNS. YINGER.
